DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIG. 1 thereof, the preferred embodiment of the new and improved rotatable electrical equipment table embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

The present invention, the rotatable electrical equipment table 10 is comprised of a plurality of components. Such components in their broadest context include a support stand 12, a support plate 14, a one thousand pound lazy susan 16, a worktable 18, a lock pin assembly 20 and an extension pole 22. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.

More specifically, the support stand 12 is fabricated of generally rectangular shaped steel tubing and includes two generally A-shaped segments 24. The steel tubing used throughout the apparatus is size 060. The sturdy construction of the stand permits it to support a significant amount of weight in the operative orientation. Each segment has two legs 26 which are angled outwardly from top to bottom. The vertical height of each leg is between about 30 and 33 inches. A top piece 28 is positioned horizontally across the upper extent of each leg. Note FIGS. 3 and 6.

A cylindrical shaped foot pad 30 is affixed to the lower extent of each leg. The foot pads include swivel means to enable the legs of the apparatus to adapt to the uneven surface of a floor. A cross bar 32 is welded to the top piece of each A-shaped segment. The width of the cross bar is between about 15 and 18 inches. The center point of the cross bar has an upperwardly extending 4 inch shaft 34. The legs of each opposing segment are coupled together by planar rectangular shaped rods 36. The rods add additional strength and stability to the apparatus. Note FIGS. 1 and 6.

A support plate 14 is fabricated of steel and formed in a planar rectangular configuration. The corners of the plate each have a circular hole 40 extending therethrough. The approximate center point of the plate is welded to the upper extent of the shaft 34. The shaft of the support stand provides the necessary clearance area for manipulation of the lock pin assembly. The plate is securely welded to the upper extent of the shaft to provide a firm base for the other components of the apparatus. Note FIGS. 3 and 6.

A one thousand pound lazy susan 16 has an upper segment 42 and a lower segment 44. Each segment is formed in a planar circular configuration. The upper segment has a larger diameter than the lower segment. The upper segment of the lazy susan is coupled to the worktable with four screws. The worktable rotates in a horizontal circular direction along with the upper segment of the lazy susan. The lower segment of the lazy susan is coupled to the pull handle. Note FIG. 3.

A plurality of bearings are positioned between the segments and permit rotation of one segment with respect to the other. The side of the table desired by the user is easily selected by rotating the pull handle. Each segment has four equidistantly spaced holes 46, 48 adjacent to their respective edges. Four bolts 51 couple the lower segment of the lazy susan to the support plate through their aligned holes. The releasably coupled components enable the user to easily dissemble the apparatus when desired. Note FIGS. 2 and 6.

A lock pin assembly 20 is formed in a generally L-shaped configuration. A first section 52 of the assembly is formed in a planar generally rectangular configuration and is affixed to the lower segment of the lazy susan. The table is easily rotated by forcing the pull handle in a downward direction and shifting it to the left or right. The second section 54 is formed as a downwardly extending rectangular box with a spring 56 positioned therein. The second section has an aperture 58 extending vertically through it. Note FIG. 5.

A pull handle 58 is formed as a spherical ball with an extension rod 60 extending upwardly from it. The rod is positioned through the apertures in the second section and coupled to the spring. The pull handle is pulled downward and shifted to rotate the table. The lower surface of the worktable has a semi-circular shaped bore at the approximate center point of each of its sides. The extension rod of the pull handle is positioned within the bores to lock the apparatus in place and prevent it from shifting during use. Note FIGS. 2 and 3.

To rotate the worktable the user simply pulls the handle downward to remove the extension shaft from its cooperatively coupled bore and shifts the handle to the left or right as desired. The user then selects the desired side of the worktable and positions the extension rod within the corresponding bore. Upon release of the handle the resilient spring forces the extension rod upward into the bore in the chosen side of the table thereby locking it in place. Each bore is approximately one inch in depth. The depth of the bore prevents shifting of the worktable during use. Note FIGS. 2 and 5.

A worktable 18 has a top piece 62 and a bottom piece 64. The pieces are fabricated of 3/4 inch particle board. Each piece is formed in a planar rectangular configuration and has an upper surface and a lower surface. The pieces are coupled together with glue and screws. The edges of the table may be painted black or any other color desired by the user. This configuration adds additional strength to the apparatus. The worktable is fabricated of strong materials to enable it to support the heavy equipment which will be placed upon it during use. Note FIGS. 1 and 6.

The top piece has a plastic coating on its upper surface. The plastic coating ensures a firm and even surface upon which to work. The bores in the lower surface are adapted to receive the extension rod in the operative orientation. Note FIGS. 1, 4 and 6. Each piece has four screw holes 66 extending through it. The bottom piece is coupled to the upper segment of the lazy susan with four screws 50 through their aligned holes. The lower surface has a semi spherical shaped bore 68 adjacent to the center point of each of its four side edges. The bores are adapted to receive the extension rod in the operative orientation. Note FIGS. 3 and 5.

An extension pole 22 is fabricated of generally rectangular shaped 060 sized steel tubing and has an upper extent and a lower extent. The extension pole is approximately 24 inches in height. The lower extent includes a planar plate 72 with screw holes 74. The plate is coupled to the center point of the table with four screws 76. The extended height of the extension pole enables the user to work with several different electrical tools at once without having to be concerned about interference from the electrical cords of the various tools. The extended height of the extension pole also enables the user to plug electrical equipment into the utility box with a minimum of effort. Note FIGS. 1 and 2.

A four outlet utility box 78 is formed in a generally rectangular configuration. The box includes four electrical sockets 80 and the associated hardware. The box is affixed to the upper extent of the extension pole. The box includes an electrical extension cord 82 with a male outlet plug. The utility box is conveniently positioned upon the upper extent of the extension pole. The utility box is adapted to receive the male plugs and up to four pieces of electrical equipment at one time. The extension cord of the box may be manufactured in a variety of different lengths to suit the user's needs. The extended height of the extension pole prevents the cord from getting in the users way when utilizing equipment on the worktable. Note FIGS. 1 and 4.

The rotatable electrical equipment table is a work stand for up to four electrical tools which can be rotated to select a particular tool. The work stand is made of three fourths inch particle board. The worktable is square, between about twenty four and thirty inches across. The worktables made of two particle boards which are screwed and glued together. A twenty four inch long extension pole is welded to a small square plate that is fastened to the center of the tabletop. A four-plug utility box is welded to its upper end. A lazy susan is coupled to the center of the lower surface of the table. A steel sheet support plate is bolted to it. Welded to the center of the sheet is a four inch shaft with tow nuts welded on one side.

A lock pin assembly is welded to the lower segment of the lazy susan. A knob is screwed to the bottom of the rod of the lock pin assembly. The rod has a washer welded to it inside the assembly. A spring pushes the washer and rod up into one of four 1/2" deep bores. Each bore is ninety degrees apart in the lower surface of the table.

The frame is made of one and one-quarter inch square tubing. Two thirty three inch high and eighteen inch wide sides join three tubes in the center of the top piece. The upper crossbar has a four inch long tube welded to its top center. The support plate is welded to the top of the shaft. Leveler bolts are fastened in the ends of the frame.

The table is locked into position by the extension rod of the lock pin assembly. Pulling the knob down allows the table to be rotated. The apparatus is sturdy and can be indexed at ninety degree increments. It is adapted to provide electrical power without twisting the cords of the tools.

As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
